SURGICAL LAMP Fild Deo. 10, 1934 ATTORNEY Patented Dec. 14, 1937 UNITED STATES PATENT OFFICE' f Austin A. Overbury. West Orange, N. J. Application December 10, 1934, Serial No. 756,756

6 Claims.

vThis invention relates to a device for illumining the oral cavity of a person and more particularly to a dental or surgical lampl which is adapted to be maintained in a fixed position within the oral r cavity or mouth of a patient while Va dental or any other surgical operation is being performed within the said oral cavity.

`It isone object of the invention to provide a means for supporting a source of light, such as an electric lamp, in a manner which will permit the` lamp to be inserted within the mouth of a patient and to adequately but comfortably clamp the said supporting means to the person cfa patient.

It is a further object to provide a clamping structure for use with a surgical lamp, which is adapted to be clamped to some convenient projecting `portion within the interior of the Voral cavity of a patient, such as the tooth or gum structure, and also to a portion of the outer facial section, as beneath the lower jaw or chin. ZIZt is also an object to provide a surgical lamp supporting means and a clamping structure which is of generally improved construction, whereby the device will be simple, durable and inexpensive in construction, Aas well as convenient, practical and efficient in use.

With the foregoing'and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts, and in the details of construction hereinafter described.

The preferred embodiment of the invention is illustratedin the accompanying drawing, wherein: i

Figure 1 is a side elevational view of the device constructed in accordancewith the invention;V

Figure 2 is a front View of the device, looking in the direction of the arrow 2 on Figure 1;

t Figure 3 isan enlarged fragmentary sectional detail takenicn the line 3-3 of Figure 2 with parts broken away; Y

Figure 4 is `an enlarged sectional detail showing a jack prongand the conductor of a conduit connected therewith; and Y v v i Figure V5 is a modied detail showing a shield for an electric lampv mounted on the Vlamp socket. A source of light and a mounting therefor, designated generally by the reference character II) is pivotally supported 0n a supporting frame structure, designated generally by the reference character Il- Said supporting frame structure includes two vertically disposed rods I2 and- I3 which are spaced apart as shown in Figure 2, and have a bracket I4 bridged across the upper: ends vto supportv said sleeve 21.

(Cl. 12S-23) thereof, also a stationary grip handle I5 bridged across the lowerends thereof. The bracket I4 may. be secured to the rod ends in any desirable manner, but is preferably constructed so as to provide a supporting shelf portion I6 also a down- 5` wardly disposed lip or jaw II.

A vertically movable clamp member I8 is slidably `mounted on the rodsV I2-I3 and preferably comprises aflat plate member having one end I9 ofthe rods I2-.I3 and between the grip handles 20 I5 and 23, to thereby provide a yieldable upward pressure upon` the vertically movable clamping member I8;V The Vextent of the upward Vmovement 0f said clamping memberV I8 is limited by the abutment provided'by the lower surface of the 25 bracket I4. Y

, YThesource of light and its mounting I0, include'an electricV lampV 25 which has a screw threaded connection with a-socketV 26, a refiector 20, asleeve 2'I securedwithin a neck on said 3o socket and a forked member 28, which is adapted Said forked Vmember is pivotally mounted on a stud 29 secured in the bracket I4 and is seated upon the anged end 3| of a bushing 32, which bushing is situated around 35 the lower end of said stud 29. The sleeve 21 is secured within thel forked member 28 by means of acollar 33, which collar is secured on an outwardly extending end of said sleeve and is fixed `against one side :of the forked member 28, while 40 the opposite side of the forked member is engaged bythe neck ofthe socket 26. Y

Current is supplied to one terminal of the electric lamp through'a conduit 34, one end of which con-duit passes through the sleeve 2T, as shown in 45 Figure `3,' andhas the end of the conductor portionthereof formed integrally with a contact button35; said button being embedded within a central cavity in an insulating washer 35,'within the lamp socket 26. The opposite end of Asaid conduit 50 passes through a exible cable 31, adjoining one end of the sleeve 21 and the upper end of the rod I2, then through a central opening or bore 38 in the rod I2. At the lower end of said rodthe V` conductor of said conduit is joined integrally with a prong 39 projecting below the rod I2, but is insulated therefrom by means of an insulatin-g sleeve 30, as shown in detail in Figure 4. Through a second prong member 4I, which is joined directly with the rod I3, the current is grounded to the other terminal of the electric lamp.

A horizontally slidable clamping means is also provided, which cooperates with the stationary jaw II on the bracket I4, and comprises a flat strip 42, having an elongated slot 43 therein, which is engaged by the bushing 32. A washer 44 is also placed over said bushing 32 and is situated between the strip 42 and the shelf portion of the bracket I4 to provide a seat for said strip. One

end of said strip is bent downward and curved somewhat to provide a jaw 45 whichis adapted to cooperate with the jaw I'I on the bracket I4. The opposite end of said strip 42 is also bent downward and has a clearance opening 46 therein which is engaged by a pin 4I projecting outward from the bracket I4. The strip 42 is thus permitted to pass over the pin 41 and over the upper surface of the washer 44. By means of a spring 48, the strip is normally biased in a direction which will tend to move the jaw 45 toward the jaw I'I, and the normal space between the two jaws is adjustably controlled by means of a nut 49, which is adapted to be screwed on a screw threaded outer end of said pin 41V. Soft elastic covers 5I-5I will preferably be placed over the jaws as shown in Figure 3.

In operation, the device will be gripped by the grip handles I5 and 23 to draw the vertically movable clamp member I8 downward with one hand, then the lamp portion will be inserted in the patients mouth. The jaws I 'I and 45, on the bracket I4 and strip 42 respectfully, are then pressed into a clamping position over a convenient portion of the too-th or gum structure of the patient, after which the outer end 2I of the vertically movable clamping member I8 is `placed in clamped engagement with the outer lower jaw or chin of the patient. After plugging the prongs 39 and 4I into a current supply socket, to light the lamp, the support for said lamp is rotated about the stud 29 to direct the light rays upon the portion of the mouth which is to be treated. It will thus be observed that Ithe light having once been set in vthe desired position, will continue to remain in such position regardless of any movement of the patients head, which feature has been found to produce a very advantageous condition when performing delicate operations on the mouth, throat, tonsils, teeth, Vetc. The lamp will preferably be of the low voltage type which will not produce enough heat to cause discomfort to the patient but if vit is desirable to use a lamp which produces a greater heat, a translucent shield 52 may be employed as shown in Figure 5. In this structure the shield may be mounted on the reflector 53 andarranged in a spaced relation to the lamp. Ventilating openings may also be provided as at 54 if desired. It will be understood that the invention may be embodied in other specic forms without departing from the spirit or essential attributes thereof and it is therefore desired that the present embodiment be considered in all respects as illustrative and not restrictive, reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.
